I was there too! I was five and I have a few memories of that trip; looking down at the teeny tiny people on the street from our hotel room several floors up (not sure which hotel), the Sinclair dinosaur, the Uniroyal ferris wheel and going to see the movie "The Yellow Rolls Royce" at Radio City Music Hall (torture for a 5-year old). I'm sure I saw it, but I have no memory of the Mustang.
Love this picture of the NY Worlds Fair 1965.
I was there! I don't remember it. I was in a stroller, most likely with a diaper full of poo. But at least I can say "I was there!"
